Which organs are involved in the respiratory system?

1. Lungs and bronchi

2. Heart and spleen

3. Kidneys and bladder

4. Ovaries and testes

The correct answer is: Lungs and bronchi

The respiratory system is primarily responsible for the exchange of gases between the body and the environment, which is essential for maintaining life. The key organs involved in this system include the lungs and bronchi. The lungs are the main organs of respiration where the exchange of oxygen and carbon dioxide occurs. The bronchi are the large air passages that lead from the trachea to the lungs, and they branch into smaller bronchi and eventually into bronchioles, facilitating airflow and ensuring that air reaches all parts of the lungs. The other organ systems listed in the options do not play a role in respiration. The heart is part of the circulatory system, responsible for pumping blood, while the spleen plays a role in blood filtration. The kidneys and bladder are part of the urinary system, dealing with waste elimination and fluid balance. The ovaries and testes are components of the reproductive system, related to the production of sex cells and hormones. Therefore, the lungs and bronchi are the correct organs involved in the respiratory system.
